Strong electrolytes have a degree of dissociation close to one, while weak electrolytes have a degree of dissociation less than one. Solvent nature: Solvents with a high dielectric constant show more dissociation. Dilution: As the solution is diluted, the degree of dissociation increases.

Explanation: Since polar satellites orbit close to the surface of the earth, it is easier to click images of the planet's surface with greater detail. Their high orbital velocity enables them to view most of the surface strip-by-stip very quickly with which high-resolution images can be constructed.

Explanation: Most communication waves cannot transmit data accurately over long distances due to the curvature of the earth. They can only do so in the line of sight. However, they are not reflected by the ionosphere like radio waves and can be relayed to a wide area using geostationary satellites.

radius of its orbit will become half.

A real gas can behave as an ideal gas if volume of molecule is negligible and interaction between molecule is negligible. This will happen if number of molecule per unit volume is very small. This is only possible at high temperature and low pressure.

If the observer is moving away from the source ((Figure)), the observed frequency can be found: λs=vTo−voTovTs=(v−vo)Tov(1fs)=(v−vo)(1fo)fo=fs(v−vov).

An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force.

Therefore, the capacity of a parallel plate capacitor directly depends on the relative permittivity of dielectric material, the permittivity of space, the area of plates, and is inversely dependent on the separation between the plates.
